IMPROVEMENT IN MACHINES FOR MAKING HORSESHOE-CALK BLANKS.

Specification forming part of Letters Patent No. 156,433, dated November3, 1874; application filed December 1, 1873.

To all whom it may concern:

Be it known that we, JOHN A. MOGEER and GEORGE H. MCGEER, of Moravia,Gayuga county and State of New York, have invented a new and ImprovedMachine for Making Horseshoe-Call; Blanks, of which the following is aspec1fication:

Our invention consists of a punch on a handlever, and a stationary die,arranged to press out the little spurs required on the end of the calkwhich is attached to the shoe for entering the punch-hole in the shoe,and making a permanent connection; and on the same lever and bed, and inclose proximity to the aforesaid punch and die, are cutters for cuttingoff the blanks after the spurs are formed, the said cutters being soarranged with the punch and (lie in order to save considerable time andlabor in transferring the bar from one machine to another, and toeconomize in expense by utilizing one bed and lever for the two devices.

Figure l is a side elevation of our improved machine. Fig. 2 is a planof the bed and section of the lever, the latter being taken on the line00 w of Fig. 1. Fig. 3 is a plan of a portion of a blank for a toe-calk,and Fig. 4 is a cross-section ofFig. 3 on the line 00 w.

A represents the bed-piece ofcast or wrought iron, to which a stronglever, B, is pivoted at one end on standards 0. D represents thestationary die for making the spurs E of the calk-blanks F. It consistsof a steel block placed immediately in front of the standards 0, withportions a, each about as long as the required length of the spurs, madeas much higher than the face I), on which the bar of which the blank ismade rests, as the thickness of the bar, which portions are separated bya space or slot, d, as Wide as the required width of the spur, and asdeep as the height of the 7 said portions or, said space or slot beingat right angles to the bar when lying on the die-face b. Directly overthis slot is a punch bit, G, fastened in the under side of the lever. Itextends downward nearly to the bottom of the slot when the lever isdown, and it projects beyond the elevation at over the die-face b ashort distance. Directly in front of the die D is a stationary shear orcutter blade, H, whose end next to the die D rises enough aboy e theface I) to prevent the bar from sliding forward when under the action ofthe punch G, and above the cutter H is the movable cutter I on the leverB.

The steel bar from which the calk-blanks are to be made is first placedon the die-face b, with the end as far beyond the die as it is requiredto have the spur E from it. The lever is then brought down, and aportion of the metal of the bar is forced out, forming the notch f vandthe spur E. The lever is then raised, the bar shifted along a suitabledis tance, and the lever is again brought down, and another spur formed.The bar is then presented to the cutters, and the blank cut off. I

Having thus described our invention, We claim as new, and desire tosecure by Letters Patent- 1. The spur-forming d'ie D, punch G, bed A,and lever B, combined and arranged substantially as specified.

2. The spur-forming die D, punch G, cutters H and I, bed A, and lever B,combined and arranged substantially as specified.
